2. FUNCTIONS OF RK STICS
1) Wiper Control
(1) Wiper MIST and Washer Coupled Wiper
The wiper relay is turned on 0.3 seconds (T1) after turning “ON” the washer switch for 0.2 ~
0.59 seconds (T2) with the ignition key “ON”, and it is turned off when the parking terminal is
turned off. 1.
The wiper relay is turned on 0.3 seconds (T1) after turning “ON” the washer switch over 0.6
seconds (T2) with the ignition key “ON”, and it is turned on three times immediately after
turning off the washer switch. 2.

02-78710-01
If the washer operating signal is inputted while the wipers are operating in intermittent or AUTO
mode, the system stores the previous intermittent interval and operates the washer coupled
wiper. After then, the wiper operation returns back to intermittent or AUTO mode with the
stored operating interval. 3.

(2) Rain Sensor Coupled Wiper
▶ System layout
This vehicle has a different wiper control logic compared to other models. As shown in the
system diagram, the rain sensor unit does not control wiper directly. The rain sensor unit sends
infrared rays signal through LED and then receives it with photo diode and then sends the
returned signal to STICS and the STICS controls the wipers directly.
For more details, refer to rain sensing wiper section in this manual.

2. Vehicle speed calculation
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
1 [pulses/sec] = 60 [km/h] x 60 [sec] / 637 pulses = 1.41 [km/h]
3. VOLUME calculation
Calculates the INT VOLUME with 5 grades as shown in the table in next page. -
4. Pause time calculation
Pause time: the duration that wipers are stopped at parking position
Elapsed time: the duration after the wiper motor started to operate from parking position
The pause time is calculated by the vehicle speed and VOLUME value as shown in the table
in next page. -
-
-
If the pause time is below 1.0 second, the wipers operate without pause.
If the pause time is over 1.5 seconds, the wipers operate intermittently. ·
